Abstract

A process is provided for producing carbon fiber yarns which comprise an intimate association of carbon fibers having an average length of between 100 and 120 mm. The process comprises transforming tows of multifilaments whose count is between 0.5 and 1 dtex by cracking, by drawing, and controlled breaking to obtain long fibers having an average length of between 100 and 120 mm. These fibers are then transformed on standard spinning equipment for long fibers into a range of yarns which have counts ranging from Mn 1 to Mn 100. The yarns of the present invention can be used for making prepreg fabrics for composites, fabrics for dry and wet filtration, fabrics for making Faraday shields, fabrics for carbonization for carbon/carbon pieces and high-performance seals.
